Cisco on Thursday announced an agreement to acquire identity lifecycle security company WideField Security to strengthen the capabilities of Splunk’s Agentic SOC.
No financial details have been publicly disclosed. WideField raised more than $11 million in Series A funding last year.
WideField has developed technology that enables organizations to discover human and non-human identities, map exposures across accounts and roles, and assess hygiene gaps.
The company’s platform also enables users to detect misconfigurations in authentication policies and weak authentication paths, providing live session monitoring for real-time threat detection, and AI-powered behavioral analytics.
By integrating this into Splunk’s Agentic SOC and Cisco’s broader data fabric, the acquisition brings deeper identity and session intelligence into threat investigations, adding critical details around credentials, active sessions, and potential impact radius.
This helps security teams better understand context for both human and AI-driven activity, and organizations gain the visibility needed to run autonomous AI systems securely at scale.
This is Cisco’s third cybersecurity-related M&A deal of 2026, after Galileo and Astrix Security.
Cisco’s announcement came on the same day Accenture revealed a major OT cybersecurity push via acquisitions totaling $4.1 billion. The professional services giant is taking a majority stake in Dragos and fully acquiring runZero and NetRise.
SecurityWeek’s M&A tracker has cataloged approximately 190 deals to date in 2026.
